BBC reports on the demise of Norway's lemmings due to global warming.Researchers writing for the science journal Nature found that Norway's warmer winters (starting about 10 years ago) have negatively affected the survival rate of the native lemmings.
Lemmings need a snow layer in order to survive through the winter and dry winters would allow more than enough lemmings to flourish and be prey.
The furry mammals are a vital part of the Norwegian wildlife food chain, and the disappearance of the lemmings has also negatively affected predatory animals such as fox and owls.
Because the warmer winters are now more humid, the researchers believe the "wrong type of snow" is causing the lemmings to die off.
